Previous treatment for varicose veins and the results of the treatment

If you take aspirin, NSAIDs or blood thinners, your doctor may instruct you on how to stop taking the medication for a certain amount of time before the procedure, to reduce the chances of bleeding. Your doctor may also advise you on your use of antibiotics and oral contraceptives.

The day before

For 24 hours before the procedure, avoid shaving or applying any lotion to your legs. Wear loose, comfortable clothing to your appointment. You might even consider wearing a pair of shorts so that your legs are exposed.
